ARTHUR BATES AND THOMAS BRIGGS, OF LEICESTER, ENGLAND, ASSIGNORS T UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPO- RATION OF NEW JERSEY.

MACHINE FOR OPERATING UPON BOOTS AND SHOES.

To all whom it may concern Be it known that we, ARTHUR Barns and THOMAS Bmoos, subjects of the King of England, residing at Leicester, in the county pecial utility in effecting the attachment of a welt or rand to the bottom face of a lasted boot or shoe.

The term welt, as used hereinafter, is intended to include within the scope of its designation various articles having the general characteristics of a welt, although not necessarily its usual functions, such as rands, imitation welts, etc.

An object of the invention is to provide an improved machine for attachino' welts which may be operated to turn out both an increased quantity of work and a superior quality'of work, which will require in its operation less labor and attention on the part of the operator than known machines and which will effect an economy in the material used.

In certain classes of work it has been the practice to attach a welt upon the marginal portion of the sole or upon the bottom face of the lasted shoe. As the welt is bent edgewise to conform it to the outline of the sole or bottom to which it is to be attached, difliculty has been experienced in causing the welt to assume the outline of the part to which it is attached where this outline changes its direction abruptly, as, for ex ample, at the sharply curved portions of the outline about the toe part of the sole or shoe.

The difficulty in causing the welt to conform to the outline of the part to which it is being attached in certain portions of said outline frequently results in unevennessof attachment and in the production of work in which the welt does not project the required distance beyond the edge of the last at all points. Even when the welt is guided Specification of Letters Patent.

to the attaching means by a guide which has been fixed in the proper relation to the attaching means to give the desired projection of the welt it nevertheless often hapending in its own plane, will be drawn back from the edge of the last at some points, especially when approaching and withdrawing from the toe portion, and at other points will with difficulty be brought into proper position to be attached.

In known machines the welt is frequently attached by metallic fastenings and the work is positioned with respect to a fixed welt guide by a. gage which bears against the upper. As above suggested, these machines are frequently unsatisfactory in operation,

the welt beyond the edge of the last the required distance at all points, and if the gage and Welt guide are so adjusted that the required projection is secured at the abruptly jection at other points will result, thereby necessitating considerable trimming to reduce the projection to the required amount.

In the preferred form of the invention the difficulty in obtainin the required projection at all points is o viated by the provision of means for effecting a relative displacement of the shoe and welt in such manner that the tendency of the welt to crowd in upon the shoe or to resist conforming to the outline at certain points may be nontralized or compensated for, and that the welt \vhen attached shall project beyond the edge of the shoe at least to the required extent throughout all parts of its outline. This result may be obtained by effecting a relative displacement of the shoe and wclt when the latter is to be attached to parts where the outline changes its direction abruptly and by maintaining the shoe and welt in substantially a uniform relation to each other while the welt is being attached to parts where the outline does not change its direction abruptly. In one aspect the invention may therefore be said to comprise means for attaching a welt to work, and -1ueans for effecting a relative displacement of the welt and the work during the attaching operation. Preferably the means for effecting the relative displacement of the since they do not insure the projection of curved portions of the last an excess of pro- Ipens that the welt, owing to its resistance to welt and the work during the attaching I work are. presented to the attaching mechanism, and in another aspect therefore the invention may be said to comprise means for attaching a welt to work and means for effecting automatically a relative displacement of the work and welt as different portions of the work are presented to the attachin means. I

In t e preferred embodiment of the invention, means is provided for iding the welt to the attaching means,.an a gage or guide is provided for locating the work with respect to the attachin means and the -welt guide- More specifica y therefore the invention may be said to comprise the provision in a machine of the class described of means for eiiecting, preferably automatically, duringthe attaching operation, a relative adjustment of the welt uide and the work gage. In the illustrate embodiment of the invention inwhich the welt is to be attached to alasted shoe, the shoe is preferably supported upon a 'ack in such manner that the jack turns with the shoe. A convenient method therefore of obtaining the automatic relative displacement of the shoe and welt at the desired predetermined points in the ath of'movement of the shoe past the attac ing means is to efiect such movement in timed relation to the turning of the jack.

When, as in the illustrated preferred embodiment of the invention, the relativedisplacement of the work and the welt is efected in timed relation to the turnin of a jack upon which the shoe is mounte it is advantageous that the turning of the shoe be substantially about an axis passing through the point where 'the insertion of the fastening takes place and in the preferred embodiment provision is made for such turning of the shoe. Moreover, provision is preferably madein' the construction of the jack for both angular and bodily ad-' just-ment of the shoe with respect to the attachin mechanism in such manner that the attac ing means which, in the illustrated embodiment, is a metallic fastening, is inserted always along the axis about which the shoe turns. Accordingly, a feature of the ,present invention comprises the provision in a machine for attaching a welt to a shoe, of a support for the shoe so constructed and arranged that the shoe may be moved with its carrier both bodily and angularly into different relations to the attaching mechanism and that the vertical axis about which the shoe turns passes constantly through the point at which the fastening inserting operation takes place and that the fastening is driven into the shoe along this axis.

A preferred construction, according to the 1 which,--

menace presentinvention, will now be described by way of example as applied toa loose nailing machine of well-known type, reference being had to the accompanying drawings, in

Figure 1 shows in side elevation the parts of the machine with which the invention is immediately associated; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a front elevationof certain of the operative parts [of the machine, the-shoe being shown 1n section; and Fig. 4 shows a shoe to which the :weltis partly attached.

. The machine in which the invention is embodied maybe of the type disclosed in the United States Patent 490,624, January 24, 1893, to L. Goddu-and to this patent reference may be had for a detailed description of parts herein illustrated but not' described. Themachine of the said" patent comprises a laterall swinging head which carries an awl 2 an a driver 4. Connected with the head to swing therewith-is araceway 6. The head is moved laterally after the awl has penetrated the work to feed the work and thenthe awl is retracted-and the head returnedto its original position to bring the driver 4 into alinementwith the hole made by the awl. The nailis then dis charged from the raceway 6 into the driver passage in the nose 8 from whichi't is driven This jack is rotatably carried by the jack" post 10 which ismounted to reciprocate vertically in an upstanding portion 12 of the machine frame 14. The jack post 10'may be raised and lowered by any suitable treadle operated mechanism (not shown) to-present the shoe 16 in position to be operatedflupon or to move it out of such position. The jack has provision for enabling the shoe to be moved lengthwise and to be tipped about axes extending lengthwise and laterally of the shoe in order that" parts of the shoe to which the Welt is to be attached may be resented properly to the fastening insertmg mechanism. A detailed description of the jack will not be attempted herein, in view of its disclosure in the application above referred to, and in View of the fact that it will not be herein specifically claimed. It will be suilicient to state that the carrier 18 for the last pin-and saddle is provided with lateral grooves 20 Whichreceive pivoted guides 22 carried'in a yoke-2i areshaped upon its lower side and arranged to slide in an arc-shaped guideway in a block or hub 26 whereby the shoemay be ti ped about its longitu inal axis as hereina" We inflation suggested. The rocking of the shoe about carried by a slide 36 adjustable in guides in the machine frame. While being attached to the shoe the welt extends between the foot plate or work abutment 38 of the machine and the shoe on the jack, as shown in Fig 3. An auxiliary guide 40, fixed upon the machine frame, supports the free end of the welt and keeps it out of the way of the operator;

A gage or guide 42, shown as a frustoconical roller, is mounted upon the slide it which is movable toward and away from the shoe in aibloclc 46 secured to the machine frame. Theslide 44 has a pin-and-slot connection 4:8 with the block 46 to limit the extent of its sliding movement To provide means for varying the extreme positions of the gage or guide a2 the block 4th is mounted to slide on a guide 50 attached to the machine frame, and can be secured in adjusted position on said guide by a screw 52 which passes through a slot in the block 46 and screws into the guide 50. The slide M is operatively connected with a cam 54: carried upon the block or hub 26 of the jack by means of a lever 58 pivoted at 58 upon the machine frame and carrying at its upper end a screw 5'? threaded through it, said screw abutting against the rear end of said slide, the lower end of the lever 56 carrying a roller 60 that engages the said cam.

In the operation of the machine the shoe 16 is placed upon the jack and the welt 32 is placed in the welt guide 3-1 and through the auxiliary guide 4.0. The jack is then elevated to clamp the welt between the foot plate or abutment 38 and the marginal portion of the sole face of the shoe, and the edge gage or guide 42 bears against the upper of the shoe adjacent to the welt, usually in the neighborhood of the shank or waist of the shoe. At this time the gage or guide i2 is in its cxtrcme rearward position which, in practice, is preferably determined by the pin-and-slot connection 4-8 of the slide -l-lwith the block &6 which supports the slide, although it will be understood that this po sition may be determined in other ways, as for example, by the shape of the cam M. The machine is now started and fastenings or nails are driven through the welt and into the insole, thus attaching them togetl'ler, the shoe being fed by the awl 2 between the successive nail driving operations. \Vhen the toe part of the shoe is reached the jack rotated by the operator in order that tho welt may be attached around the said part. This rotation of the jack brings the cam 5 L thereon into engagement with the roller no on the lever 56, thus moving the lover and through it the slide -14; that supports the r gage or guide t2. 'lhe gage or guide -l-:3 is

thus forced forwarr lly in the machine and eli'ects the relative displacement ol the shoe 116 and the welt 32 for the purposes hereinab'ove referred to. .the jack moves the cum a l out of engagement with the roller 60 and lever 56 and permits the gage or guide l2 to be returned Continued rotation of to its retracted position either by the pressure of the work against it, or by the action jof a spring or the like, by which time the welt 32 will have been attached around the toe part of the shoe.

It will be noted that the jack is so constructed and arranged that it turns about the jack post 10 which is so located that its extended axis passes through the point at which the nails are driven. in this construc tion, therefore, the jack post 10 always receives the direct blow of the driver regard less of the adjustment of the carrier 18 with respect to the post or with respect to the inserting mechanism.
